WARREN W. DUTOHER, OF MILFORD, MASSACHUSETTS.

IMPROVEMENT IN ROLLER-TEMPLES FOR LOOMS.

Specification forming part of Letters Patent No. 37,954, dated March 24, 1863.

To cLZZ whom t may concern:

Be it known that I, WARREN W. DUTCHER, a citizen of the United States of America, and a resident ot' Milford, in the county of Worcester and State of Massachusetts, have made a new and useful invention having reference to roller-temples for weaving-looms 3 and I do hereby declare the same to be fully described in the following speciiication, and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a side elevation, and Fig. 3 a front end view, of a temple provided with my invention. Fig. 4 is a transverse section taken in the line of and through the axis ofthe toothedroller of the said temple. Fig. 5 is a section taken perpendicularly to the axis of the said roller.

The nature ot' my invention is found in eX- tending the cap ot the temple-roller down across the inner end ot such roller, and to a level with or into the trough thereof, and making the said trough with a closed inner end, or the equivalent thereof, the whole being so as to preventthe toothed roller of the temple from injury arising from a blow of the shuttle either against the inner end of the roller or against the teeth of such roller. My invention is also found in not only so constructing a temple that the two ends of both its trough and cap shall be closed, but so that the cap and the trough maybe in two separate parts, connected or combined together by means of one or more screws, or the equivalent thereof. I would further remark that my said temple is an improvement with reference to that patented on the 24th day ot' April, A. D. 1860, by J. H. Woodward, his Letters Patent being numbered 28,043 5 as while I make the trough with a closed inner end, as he does in carrying out his invention or improvement, I combine therewith, or with a temple so made, an extension ofthe cap ofthe temple-roller downward over or across the inner end of the said roller and down into the trough, whereby, by means of such extension and the closed inner end of the trough, I am enabled to afford a better protection to the roller, with respect to the action ofthe shuttle, than is the case when the roller-cap has no closed end or no such extension.

In the drawings, A denotes the trough of the tempe, as made with a closed inner end, as shown at a., while B is the toothed roller, and O the cap or cover thereof. The extension of the said cap down by and across the inner end ot' the roller, and into the trough, is shown at b. This extension serves as a means of supporting the inner end ofthe shaft c ot' the roller, the opposite end of such shaft being projected from the outer or standard portion ci of the trough. The cap and the trough, instead of being formed in one solid piece, in the usual manner, or in two separate parts, connected by a hinge, as in temples where the cloth rests on the top of the roller, are in two separate parts, and are rinly connected or fastened together by one or more screws, s s, or the equivalent therefor. Were it not for this mode ot' making the templetrough and its caps it would be difficult, it' not impossible, when both ends of the trough and both ends ot' the cap are closed, to get the roller into and out ofthe temple. A temple made in my improved manner not only has its roller protected from the shuttle, but has all of the advantages ofthe improvement as patented by the said Woodward. lt is well known that when the inner end of the cap ofthe roller is open the shuttle, while deiected from its true course across the racebeam, is liable to enter the cap and split or more or less injure the roller. Although the closing of the inner end of the trough operates in a measure to protect the roller it does not entirely accomplish suoli, but when the guard or extension b of the cap is employed with the cap and with the trough, made with its inner end closed, there will be a perfect protection to the roller from a blow from the shuttle.

I do not claim making the trough alone with a closed inner end, or its equivalent; but

I claim- 1. In combination with the trough so made, and with the cap of the roller, the extension I), arranged so as to project downward from the cap and across the inner end ofthe roller, substantially as described.

2. The improved temple, made not only with its cap and trough closed at both ends of each, but having such cap and trough formed in two separate parts and connected together by screws, or their equivalents, as specified.
